Last Wednesday I was using the garmin on my bike and the battery went off. After that is impossible turn off the device. When I connect the garmin to the computer/energy, it turns on and it does not work correctly. I want a full reset in order to know if I can use it again.

Re: My Garmin 305 edge does not work correctly
Hi my own 305 has been doing this also you can perform a soft reboot by pressing the Mode and reset button together for approx ten secs,this will turn unit off and you will lose data but it should stop the problem however if you have a power problem with internal contacts then Contact Garmin, also you can download webupdater for garmin at this address http://www8.garmin.com/support/collection.jsp?product=999-99999-27

First thing to check for is the battery of the device. If it is bad, it will not turn on the edge. Try to use a friends battery to see if it will turn on. if it does, then it means the battery is what you need to replace.
But if it is not the battery, then you need to check the charger of the edge if it is still okay, then you need to check the connection port on the edge.
It is definitely not a software problem because if it was it, then the device will turn on but will not get pass the garmin nuvi page.
Would be glad to know if the information was of help to you.
Soft reset : hold mode and lap/reset buttons for 10 seconds Hard reset : device should be powered down, hold start and mode buttons for 3 seconds then pulse press the lap/reset button.
After soft reset, you need to hold start button for up to 10 secs before it starts.
After hard reset, you will loose all your data, including profiles
Now if this does not work, you should check battery. Does the device charge when plugged on PC ? If it does not, either battery is out of order or the contacts inside the device re broken. This may happen if device is used in continuous vibrating environment like mountain bike.
Changing battery or fixing contacts issue is explained there :
Could be yes. There are contacts inside the device that become sensitive to vibrations after a while.
I have seen on Internet that it may also be due to USB plug that acts on these contacts. Anyway in this situation there is no other way than opening the devices and soldering contacts or adding wires to replace these contacts.
As opening device is not at all easy, I recommend you send your device to Garmin support.
Otherwise please check the relevant procedure on the internet
Have had this happen to me also, try pressing the mode and reset at same time also try lightly tapping frame of garmin on desk (easy though). if this still fails put it on your bike and go for spin???
hope first suggestion works as it did fr me
If you have the time and patience then log onto garmin and download the webupdater then join the garmin site and plug in your 305 garmin dashboard will update for you and possibly fix it, other than that you will have to send it to garmin, if its still in warranty, 75 dollars if its out of warranty
Hello there: you might want to remove the battery and inspect the connection pins if one of them are bent or loose they will cause this also a loose connection internally will cause this. if this is a warranteed item you might consider using it ok? best regards michael
Pairing the Edge 305 and sensors
Once you have installed the Garmin Edge 305 and the
cadence sensor they need to be paired. As they communicate wirelessly
with each other the Edge needs to connect to each sensor before it can
receive input from it.
The initial pairing needs to be done away from other
wireless systems this allows the Edge to pick up the sensors it is
supposed to be monitoring. This is a little like black magic, but it
seems to work quite easily.
The cadence sensor has a small press contact which puts the sensor into pairing mode. The HRM just seemed to connect by itself.
Subsequent pairing is much faster as the Edge 305 seems
to remember which sensors it is paired with. If you have problems or
need to change one of the sensors then you can use a setup feature to
either turn the sensor off or to re-pair it.
